Question

I need to retrieve columns from two tables and I have used an INNER JOIN. But its consuming lot of time during loading the page. Is there any better and faster way to achieve the same?

Select P.Col1, P.Col2, P.Col3, P.Col4, P.Col5, C.Col1, C.Col2, C.Col3 from Pyalers P inner join Customers C on C.Col1 = P.Col1 where P.Col2 = 5

Thanks in Advance.

Without knowing your DDL, there’s no way to say.

But conceptually this is ok, just be sure you have proper indexs sets.

For instance: (is your table name really ‘Pyalers’? Assuming ‘players’)

CREATE INDEX idx_players ON `players` (col1);
CREATE INDEX idx_customers ON `customers` (col1);

use the columns you need for joinning the 2 tables.
